7800GTX & Zalman VF700

**Cordovader** · 08-25-2005, 03:02 AM

Hi all, after reading the Zalman forums iÂ´ve tried to fit the Zalman VF700-CU & everything went great

(well, almost great..)

Here are some pics:

As you can see iÂ´ve had to put some Zalman memory heatsinks because the Revoltek ones didnÂ´t fit in some places.

After installing it the temps went from 53/76 to 45/63.

ItÂ´s early for the final results but for the moment this is the maximum stable clocks iÂ´ve reached:

nice!

what clocks were you able to reach before??

**Cordovader** · 08-25-2005, 05:35 AM

510 on gpu, memos hasnÂ´t changed.

**Squid_Spit** · 08-25-2005, 07:06 AM

Nice, didn't really the zalman would be this much better than the stock cooler

**higgins** · 08-25-2005, 07:23 AM

nice, ive got the zalman on the way, hoping for similar results

**Vapor** · 08-25-2005, 07:23 AM

IDK if I have a buggered core or what, but I didn't gain 25MHz from going from stock cooling to watercooling. I gained 5MHz and my temp drop was much more than that (it was also cooler running to begin with). In fact, I gained more on my memory....not to hijack, but maybe you know of something I'm doing wrong?

**chinkgai** · 08-25-2005, 01:04 PM

no, thats just how they are...voltage starved from what i read

**rick_fx** · 08-25-2005, 09:44 PM

Look at his sig properly Mike6969, he has 1gb Redline also

**Cordovader** · 08-26-2005, 12:18 AM

Currently iÂ´m using 2x256 KHX3500 old BH5 for testing

Redlines are in a "burning session"

Vapor: I supose gpuÂ´s are like cpuÂ´s, you never know how far will they go, independently of the cooling. I have this problem with my 3700, topped out at 2850 & water (even using ice) didnÂ´t help me to reach much more stable.

By the way, yesterday iÂ´ve tried again the same config for 05 (535/1340) & everything were full of artifacts. iÂ´ve had to slowdown the core to 520 to work correctly.

However, pushing memos to 1400 didnÂ´t gave me any problem.

Somedays i can push the core over 500 without problems & other days, using the autodetect option of coolbits it stops at default cores.

That happens as much with the stock cooler as with the Zalman.

Any idea?

Also iÂ´m looking for a moded bios that let me push the voltage to 1,5 without any hardmod. Stock voltage is 1,4v right?(maybe iÂ´m wrong you will tell

)
IÂ´ve read that with some mode bios this is possible. Also iÂ´ve tried to modify one with NiBiTor 2.4 but the limit were 1,4v.

I would appreciate any comment/suggestion.
Thanks guys

Show them that KHX Powa!!

What happened with the Geil ONE kit? I've never heard results from them...

C you and good luck!

**Cordovader** · 08-26-2005, 07:47 AM

Hey Besaid

Between today & tomorrow i will test the oneÂ´s

Sorry for the offtopic

Back to the theme, any moded bios for the 7800GTX? I need more voltage

**EZClock** · 09-03-2005, 09:08 PM

Awsome, im definetly getting one of these for my 7800, just until I get my 650 I can start to test.

**ZeroX** · 09-04-2005, 03:17 AM

Hey, that zalman is doing so well

Ask him for the bios (http://www.xtremesystems.org/forums/...d.php?t=73290),... he has a pretty good clocks.

Regards

Here is my score. I think you should get more than 9100 in the score as your cpu was oc to 2.8ghz. My core was 515 and 1355 for the memory on stock cooler.

will two of them fit in your board.

ps..
sorry off topic

Welcome to XS evaseeker!

**IvanAndreevich** · 09-10-2005, 11:22 AM

I get better temps than you get with the Zalman simply by replacing stock fan with an 80 mm one. Although, I imagine it's louder.

Two will fit on DFI board but its very tight and the top card will suffer nuless you can force some cool air in between the cards.

How about Asus AN8-SLI Premium? Would two vf700 fit on that board?

**Kris** · 09-11-2005, 01:35 PM

Two should easily fit on that board and get better temps than the DFI. My top card runs about 6 to 10c hotter than my lower card.

**jetjaguar** · 09-12-2005, 09:56 PM

yeah i have 2 gtxs on the dfi board and i had to pull one out for the time being since it was running so hot .. like 60c idle .. bottom one was like 49-50c idle .. both loading high 70s low 80s .. so im either switching boards to the asus one since the spacing is so much better or getting some better cooling that vents the air out of the case

**Dave338** · 09-13-2005, 11:24 PM

Congratulations Cordovader

Nice results.

Salu2.

**toledo** · 10-08-2005, 06:13 PM

LOL .... Unless you have 288Mb of Ram in you card you put an extra ramsink in a wrong place . ..... or maybe only 3 chips in the back of the card

Nice results , BTW

**Cordovader** · 10-12-2005, 01:25 AM

It was a chip (donÂ´t know what kind).

I saw naked & didnÂ´t like it xD

**JaCk0** · 10-12-2005, 11:58 AM

good job, nice screens and temps ^^.

EstarÃ¡ esto en N3D?

Regards.
